份時,則該凹槽、冷卻肋、薄片及/或鰭片亦可配置在該外 Ο 殼之外側上,即,該外殼壁之外側上。 除了第一冷卻體之外,第一基體本身亦可具有第二冷卻 體。於是,第一基體亦可形成第二冷卻體,其上配置著該 至少一第一 LED。除了經由第一導熱管和第一冷卻體將熱 排出以外,第二冷卻體可使該至少一第一 LED之排熱量提 高。由於第一冷卻體和第二冷卻體配置在該機場照明裝置 之外殼中,則該至少一第一

Field of the Invention The present invention relates to an airport lighting device as described in the preamble of claim 1, which has at least one light emitting diode. [Prior Art] In order to take off and land an aircraft, for example, in the dark and in smoke, the take-off and landing orbits shall use a so-called airport lighting device, which may, for example, indicate the lateral boundaries, the center, the start and the end of each track, and Individual sections can also be marked. Therefore, such lighting devices must comply with official regulations and should have high reliability and longevity. SUMMARY OF THE INVENTION At least one object of certain embodiments of the present invention is to provide an airport lighting device having at least one light emitting diode. The above object is achieved by an object having the features of item 1 of the independent scope of the patent application. Advantageous embodiments and other forms of the object are described in the appended claims, and the description and drawings are additionally described in the following. According to one embodiment, the airport lighting device comprises, in particular: At least one first light-emitting diode (LED) on a substrate, a first heat transfer tube having a heat transfer medium, a first heat sink, and a casing, wherein the first substrate and the first heat pipe are disposed Wherein the first heat pipe is thermally coupled to the first substrate and the first heat sink, and the heat transfer medium can be circulated in the first heat pipe to cause at least one first light emitting diode 200933081 to be generated during operation. Heat may be discharged from the first substrate to the first cooling am body. Halogen lamps or halogen-reflecting lamps are commonly used in airport lighting to produce light. These lights usually have hundreds. The operating temperature of c is high and therefore has a high heat loss power. Compared to halogen lamps, LEDs can have much smaller heat loss power and at the same time have high lifetime and reliability. However, in the airport lighting device described herein, in order for an LED to achieve a life like at least one first LED, the temperature in each layer of the LED that generates light must be maintained at a critical value. Under the limit, the premature degradation effect does not occur in the LED, otherwise the life will be shortened. For example, the temperature of the barrier layer in the LED must be maintained at a temperature of 125 t and preferably maintained below 90 ° C in a continuous operation. Conventional heat sinks in halogen-reflecting lamps are too small to be effectively cooled and the heat generated by at least one LED during operation cannot be sufficiently efficiently via a metal circuit board or by free convection on the outer casing. When discharging, the heat generated by the at least one LED can be effectively conducted by the first heat pipe from the first substrate to the first heat sink. The at least one first LED can be disposed on the first substrate such that the at least one first LED can be in thermal contact with the first substrate. The heat generated by the at least one first LED during operation can thus be transferred to the first substrate via a contact surface having the first substrate. Heat can be additionally transferred to the first heat pipe by thermal contact between the first substrate and the first heat pipe. Thus, the first heat transfer tube can have a first partial region and a second partial region, so that heat can be transferred from the first partial region to the second partial region by the heat transfer medium. It is particularly advantageous that the first portion of the first portion of the 200933081 and the second portion of the region are the mutually facing sides or ends of the heat pipe. The first partial region is thus in thermal contact with the first substrate. The second portion of the region is in thermal contact with the first heat sink. The first heat pipe may additionally have an inner volume completely surrounded by an outer wall in which the heat transfer medium is present. The first portion of the region is preferably disposed on the first end of the heat pipe. The first heat pipe is particularly suitable for transferring heat (i.e., 'thermal energy) from the at least one first led to the heat transfer medium in the first partial region. The heat transfer medium converts at least a portion of the first partial region from the first state to the second state, wherein the first and second states may be, for example, different Aggregate states. In particular, the first state may comprise a solid phase and/or a fluid phase and the second state has a phase in the form of a vapor. This means that the heat transfer medium can evaporate or sublime in the first partial region by absorption of heat from the heat source. Thus, the heat transfer medium can have a first vapor pressure in the first partial region. Alternatively, the first state may also include a phase in the form of a vapor. Q The density of the second state is preferably less than the density of the vapor phase of the first state. At least a portion of the heat transfer medium is in a second state after absorbing heat in the first partial region, and then the at least a portion of the heat transfer medium can be moved to the second portion by, for example, convection The portion is preferably disposed on the second end of the heat pipe. In the second partial region, the heat transfer medium is again switched from the second state to the first state by thermal discharge (i.e., condensation or sublimation). In particular, the heat transfer medium may have a vapor pressure of -7-200933081 in the second partial region, which is less than the first vapor pressure. The heat released by the transition of the heat transfer medium can be discharged to the environment (especially the first heat sink) by the second partial region. In particular, the principle of action described above is based on the condition that the temperature of the first partial region is higher than the temperature of the second partial region. Then, the heat transfer medium in the first state in the second partial region can be transferred back to the first partial region by, for example, a force or a plurality of forces (generally gravity and/or capillary force). . In particular, it is suitable to use a mesh structure, a sintered body structure, a groove or a slit or a combination of these forms (which are disposed in the inner volume or in a manner surrounding the inner volume), by capillary action The force is transported from the second partial area to the first partial area. For example, the first heat pipe can transfer thermal energy through the heat transfer medium according to the above principle. The first heat pipe can be (or include) a thermosiphon or, in particular, a heat pipe. Such a heat pipe operated in accordance with the above principles advantageously enables efficient transfer of thermal energy from the first partial region to the second partial region in an economical manner without the need for additional energy consumption. In particular, the airport lighting device can have a heat pipe as the first heat pipe that, when efficiently transferred by the heat transfer medium, can have an installation orientation required for operation of the airport lighting device. This is related to the direction of gravity and/or the direction of extension of the airport. This means in particular that the first heat pipe extends horizontally from the first substrate to the first heat sink in the above-described mounted state of the airport lighting device. 200933081 The first heat pipe can have a long rod shape. Here, the first heat pipe may in particular have a circular cross section perpendicular to the longitudinal axis. The first and second partial regions of the first heat-conducting tube are thus formed in an advantageous manner by the end regions of the bars. Alternatively or additionally, the first heat transfer tube may also have an elliptical or etagonal cross section, where n is an integer greater than 3 or equal to 3. Further, the first heat transfer tube may have a plurality of mutually separated inner volumes having the heat transfer medium in the inner volume. The first heat pipe may also have a plurality of heat pipes, which may be in thermal contact with the first substrate and the first heat sink independently of each other or may be integrated into a common member, for example, two depending on the length. Connected rod-shaped heat pipe. Furthermore, the first heat transfer tube can also have an extended form or a form of at least a bend in a partial area. The first heat pipe is thermally coupled to the first substrate and the first heat sink, which means that the first portion of the first heat pipe is in thermal contact with the first substrate, and thus is also disposed in the first At least one first LED on the substrate forms a thermal contact, and a second portion of the first heat pipe is in thermal contact with the first heat sink. © The above thermal contact or thermal coupling can be achieved by mechanical contact, for example, by the contact surface or contact area on the first heat pipe, the first substrate and the first heat sink. In particular, the first base body and/or the first heat sink can thus have a bore, a recess or an opening to form a contact surface into which a portion of the first heat pipe extends inwardly into the bore, groove or opening. A portion of the middle and/or first heat pipe extends into the bore, the recess or the opening. Thus, each contact surface or contact region can be modified by a thermally conductive connecting medium, such as a thermally conductive paste and/or a soldering agent having a solder 200933081 agent, wherein the thermally conductive paste is applied to each of the first heat pipes. The first base body and/or the first heat sink can be loosened by a type. The cork can include mechanical fastening means, such as bolts, combinations of the above. In addition, after the first heat conduction, it is not easy to loosen or under normal conditions, it cannot be loosened, welded, fused, bonded or a combination thereof, and connected to the body. The first heat pipe may also be connected to the first substrate and/or the first heat sink by two or combinations, i.e., bolts, plugs, flanges, and clamps. The heat transfer medium preferably has water. The other side has ethane, propane, butane, pentane, methylamine toluene, acetone and/or carbon dioxide or above. For example, the heat transfer medium may have water and freeze protection so that the first heat pipe can also be in water. Below the freezing point, the body remains a fluid phase. In addition, there is mainly a small but small pressure in the inner volume compared to the volume inside the first heat pipe. Another way is that the air pressure in the inner 1 environment is still high. By force, the choice of the heat transfer medium and, e.g., the choice of length, can be used to adjust the form, the thermal coupling surface or the contact area between each other. The fixing means is connected to the opening, in particular the insertion, the flange, the clamping or the tube by means of a fixed manner, for example, the first base body and/or the first cold type of the above-mentioned fixing manner, welding 'Fusion, bonding, the formula, the heat transfer medium, ammonia, methanol, ethanol, a mixture or combination of three. The protective agent, for example, alcohol, has at least a part of the heat medium, the air pressure in the environment, and the air pressure in the environment. [There may also be a first heat pipe that adjusts the pressure in the inner volume. Example of size: diameter and expected temperature range - -10-330330. The first heat pipe in this temperature range can operate efficiently. Especially for airport lighting, due to official regulations, the above adjustments need to be reliably and continuously operated in the temperature range of -55 °C to +55 °C. The first heat pipe may additionally have a material having a high thermal conductivity, particularly a metal such as copper or aluminum. In particular, the first substrate may also have a material having a high thermal conductivity, in particular a metal such as copper or aluminum. Further, the first substrate may be, for example, or have a metal core circuit board such as an aluminum core circuit board. Thus, the first substrate can have mechanical or electrical contact areas and contact faces, such as mounting faces or conductive tracks, whereby the at least one first LED can be mechanically and electrically connected. Further, the first heat sink can form at least a portion of the outer casing, wherein the at least one first LED is disposed on the first substrate. This means that the first heat sink, for example, can form part of the outer casing wall adjacent to the at least one first LED on the first substrate of the environment of the airport lighting device. Thus, it can be ensured that the heat of the at least one first LED can be efficiently discharged into the environment of the airport lighting device via the first substrate, the first Q-think and the first heat sink. The first heat sink may be formed and disposed around the first substrate. This form of first heat sink can thus be spatially arranged around the first substrate to form a compact airport lighting device. In particular, the first heat sink can enclose the first substrate so that the heat of the first heat sink can be symmetrically discharged into the environment of the airport lighting device in the same form. For example, the first heat sink may be cylindrical, having a circular, elliptical or triangular or polygonal cross section or a combination of these forms. -11- 200933081 In addition, the first heat sink has a material having a high heat conductivity of a metal such as copper or aluminum. Especially when the ratio of the surface of the first cooling body to the volume is high, it is advantageous. Therefore, the heat sink preferably has grooves, cooling ribs, sheets and/or fins. Thus, heat can be discharged to the environment over a large area and efficiently. For example, the first heat sink may have a plurality of grooves, cooling ribs, sheets and/or fins on a surface away from the first substrate to surround the first substrate. In particular, when the first heat sink forms at least a portion of the outer casing, the grooves, cooling ribs, sheets and/or fins may also be disposed on the outer side of the outer casing, ie, the outer side of the outer casing wall on. In addition to the first heat sink, the first substrate itself may also have a second heat sink. Thus, the first substrate can also form a second heat sink on which the at least one first LED is disposed. In addition to discharging heat through the first heat pipe and the first heat sink, the second heat sink can increase the heat rejection of the at least one first LED. Since the first heat sink and the second heat sink are disposed in the outer casing of the airport lighting device, the heat of the at least one first LED can be discharged into the inner space of the outer casing via the second heat sink. This is advantageous when the temperature in the environment in which the airport lighting device is configured is low enough that the heat transfer medium in the first heat pipe is not operating at the at least one first led, completely or at least one large The portion is frozen' such that immediately after the at least one first LED is activated, the heat transfer medium in the heat pipe cannot circulate or cannot be fully circulated, so the heat generated by the at least one first LED cannot be efficiently The ground is discharged to the first cooling body. With the second heat sink, the heat generated by the at least one first LED can be discharged into the inner volume of the outer casing, and thus redistributed, so that the temperature in the outer -12-200933081 shell and the temperature in the first heat pipe It can be higher than the ambient temperature, so that the heat transfer medium in the first heat pipe can be fully circulated. Alternatively or additionally, a heating element may be disposed in the outer casing to heat the first heat pipe to heat the first heat pipe to an operating temperature required for heat removal. In particular, the operating temperature may be utilized for the heat transfer. The melting point or boiling point temperature of the medium is set. In the above airport lighting device, the electrical power of the at least one first LED is not necessarily limited by the preventable risk of overheating of the LED in the housing. Conversely, the at least one first LED can have an electrical power greater than 20 watts. As in high power LEDs, the heat rejection described herein allows the airport lighting device to achieve a long service life by means of the first heat pipe and the first heat sink. Additionally, the at least one first LED can also be or include an array of LEDs that are formed from a plurality of identical or different LEDs on the first substrate. The LEDs of the at least one first LED or LED array preferably emit light in the visible wavelength range that creates a colored, mixed color or white illumination impression in the viewer. The characteristics of such LED arrays and LEDs have been known to experts in this field and will not be described here. The airport illumination device may have at least one second LED on the second substrate in addition to the at least one first LED. In addition, the airport lighting device can have a second heat pipe that is thermally coupled to the second substrate and the first heat sink and includes a heat transfer medium that can be in the second heat conduction when the at least one second LED is operated Loop in the tube. Thus, heat generated by the at least one second LED can be discharged into the first heat sink by the second substrate. -13- 200933081 The second substrate may have features like the first substrate described above. The second heat conduction has the features of the first heat pipe as described above. The at least one second LED can be characterized by at least one of the first LEDs. In particular, the first substrate and the second substrate must be disposed in the housing to enable a first LED and the at least one second LED to emit light beams in opposite or different directions during operation. Further advantages and advantageous embodiments of the above described airport lighting device will be in the embodiment shown in Figures 1 to 2B below.

The at least one first LED 1 is disposed on the first substrate 2 The first substrate 2 serves as a mechanical carrier and has electrical leads for connection to the at least one first LED. In this embodiment, the first substrate 2 is formed of an aluminum core substrate that is in thermal contact with the at least one first LED 1. In the inner volume of the first heat transfer pipe 3, the first heat transfer pipe 3 having the heat transfer medium 31 is in thermal contact with the first base body 2 and the first heat sink body 4. The heat transfer tube 3 is formed such that the heat transfer medium 31 can circulate in the inner volume of the heat transfer tube 3, and heat generated when the at least one first LED 1 is operated can be discharged to the first heat sink 4. In addition, the airport lighting device 100 includes a casing 5 having a cover portion 51 and a lower portion 52, the two portions including an inner casing volume 50»the at least one Q-th LED 1 disposed on the first base body 2, and The first heat pipe 3 is disposed inside the outer casing 5 to form a first heat sink 4, so that the heat discharged from the at least one first LED 1 to the first heat sink 4 can be discharged to the environment by the first heat pipe 3. In the present embodiment, the heat is discharged into the recess 97 of the airport 98. Thus, the first heat sink 4 is in thermal contact with the wall of the lower portion 52 of the outer casing 5. In addition, a heating element (not shown) is mounted in the inner volume 50 of the housing for heating the first heat pipe 2 to an operating temperature required for heat removal, as described above. -15- 200933081 Other optical, electrical and mechanical components, for example, windows, lenses, electrical conductors in the cover 5 1 and components or mechanical fixtures for the various components described herein are not clear display. However, these components can be additionally configured in the volume 50 within the housing. In addition, electrical recesses and/or components, such as transistors, may be disposed in the recess 97 outside the outer casing 50, and extended to the airport lighting device via appropriate plugging and/or guiding (not shown). 100 in. In addition to the airport lighting device 100 that is lowered to the bottom as shown here, the airport lighting device 100 can be configured, for example, on one of the support devices above the airport 98, such as a pole. 2A, 2B shows a three-dimensional spatial display of another embodiment 200 of an airport lighting device, wherein FIG. 2A shows only the lower portion 52 of the outer casing 5 in comparison with the first drawing, the cover being shown for clarity. The part 51 has been omitted. Fig. 2B shows only the components disposed in the interior of the casing 5 in Fig. 2A for easier understanding in comparison with Fig. 2A. The following description refers to both Figures 2A and 2B. The airport illuminator 200 has a heat sink 4 which forms part of the lower portion 52 of the casing. The heat sink 4 has a cylindrical form and encloses an inner volume 50 in which a first LED s 1 ′ is disposed on the first substrate 2 and a plurality of second LEDs 6 are disposed on the second substrate 7 . Each of the plurality of first LEDs 1 and the plurality of second LEDs 6 respectively displays, for example, two LEDs each having an optical element to shape the beam. These first LEDs 1 and second LEDs 6 are configured to independently emit light beams in mutually different directions. -16- 200933081 The first base body 2 and the second base body 7 respectively form a second heat sink having cooling fins 21 or 71, respectively, such that at least a portion of the heat generated by the operation of the LEDs 1 or LEDs 6 is as described above The mode is discharged into the volume 50 within the housing. The first heat pipe 3 is thermally connected to the first substrate 2, at which time the end of the first heat pipe 3 is inserted into the opening of the first substrate and the first heat pipe 3 is offset by the first substrate 2 The curved form extends to the first heat sink 4 . The first heat transfer tube 3 has a spiral-like form which is adjusted in accordance with the inner side of the first cooling body 4 facing the first and second base bodies 2, 7. The first heat transfer pipe 3 is thus arranged along the inner face of the first heat sink 4 in a form surrounding the first base body 2. The first cooling body 4 has a further λ, and the first heat transfer pipe 3 is disposed along the half of the inner circumference of the first cooling body 4 in the slit. This makes it possible to form a large area of thermal contact between the first heat pipe 3 and the first heat sink 4. The second heat pipe 8 is thermally connected to the second substrate 7, wherein the second Q heat pipe 8 is inserted into the opening of the second substrate 7, and the second heat pipe 8 is like the first heat pipe 3, It is in the form of a spiral and is also arranged in the slit in the first heat sink 4. The first heat pipe 3 thus extends along the inner face of the first heat sink 4 to the second base body 7, and the second heat pipe 8 extends along the inner face of the first heat sink body 4 to the first base body 2. In particular, it can be seen from Fig. 2B that the first and second base bodies 2, 7 and the first and second heat transfer tubes 3' 8 can be most closely arranged in the inner volume 50 of the outer casing, and at the same time can be in the heat transfer tube 3' 8 A large area of thermal contact is achieved between each of the first and second cooling bodies 4 . -17- 200933081 The heat pipes 2, 7 are disposed at the height of the LEDs 1, 6, or may be disposed below the heat pipes 2, 7 in this embodiment. In an installation state of the airport lighting device 200, as shown in Fig. 1, the heat transfer pipe 3' 8 extends in the horizontal direction along the first heat sink 4. The relationship of "horizontal" with respect to the direction of gravity has been defined in an installation state of the airport lighting device 200. This means that the installation orientation of the airport lighting device 200 is such that the cylindrical axis of the first cooling body 4 is parallel to the direction of gravity in the mounted state in this embodiment. The heat sink has a plurality of cooling ribs 41 on the outer surface away from the first and second base bodies 2, 7, i.e., on the outer side of the outer casing, around the respective base bodies 2, 7. Thus, the first heat sink 4 can be thermally coupled to the environment over a large area, and thus the outer casing of the airport lighting device 200 can also be thermally coupled to the environment over a large area, which is generally referred to as the airport shown in FIG. The notch. Therefore, it is ensured that the first cooling body 4 can efficiently discharge heat into the environment. In addition to or in addition to the vertical cooling ribs shown, the first cooling body 4 can also have cooling ribs or cooling fins that surround the inner volume 50 of the housing horizontally or obliquely in the radial direction.
